If your gums are bleeding when you engage in normal brushing and flossing, even a little bit, there is likely a problem. You can verify with your dentist and get a diagnosis from him.
However, most of the time, the problem will be indicative of gum disease. This can range from mild gingivitis to the more severe forms of the disease. However, in either case, you will want to take action.
Initially, you want to arrest the progress of the disease and secondarily you will want to prevent it from coming back. Part of the problem rests in lack of education.
You might be surprised to learn that the majority of people have some form of gum disease. However, just because that is true does not mean you should take it lightly. In fact, gum disease is the number one cause of tooth loss.
Amazingly enough, some people have lost teeth and have had implants or dentures without ever understanding the cause of their problem. This is very sad. If you think about a rock growing out of your hand, you can understand how fragile and vulnerable the tissue might be to infection. This is similar to the issue in your mouth.
When you think of it that way, it may be easier to recognize how prevalent the problem is. If that does not do it for you, you can simply fall back on the statistics. Ask any professional, up to 75% of the population has some form of gum disease right now.
Besides brushing and flossing, there are additional things you can do to fight gum disease. It is well worth your time to learn what works beyond mere brushing and flossing
